BASIL CARLISLE LOW', OE AUCKLAND, NEW ZEALAND.

STIRRER 0B. MXER readies.

To all whom, 'it may Concern.'

Ee it lrnown that Basin Cannisnn Low, a citizen of the v Dominion of New Zealand, residing at Hellabyds Building, Queen Street, Auckland, blew Zealand, has invented ceri tain new and useful lniproveinents in Stirrers or Mixers, of which the following is a specification.

VThis invention relates to apparatus fitted to the covers or lids of vessels or containers, and operated for the purpose of stirring or mixing the contents thereof, and its object is to provide improved means for the aforesaid purpose. y

According to the invention two plates secured together are fitted on the cover or lid ofa vessel or container and between said plates a pinion and driving wheel are located, the pinion being mounted on the upper end of a short central shaft passing through the lower plate and said cover or lid, and with said driving` wheel is housed in a raised portion of the upper plate.

A crank handle is fitted on the upper end of a spindle which passes upwards through the upper plate and is slotted at its lower end to fit over a pin accommodated in grooves and so as to lay across the central opening of the driving wheel.

A metal strip bent to provide parallel sides and a. connecting portion is passed on the central shaft below the cover or lid, and is secured to said shaft by a cross pin, so that spaces are left between the parallel sides of the strip and said shaft.

`Beaters or blades with hooks at their upper ends are pivotally secured to thev central shaft by being` hung on the cross pin, in the spaces between the shaft and the sides of the strip, at opposite sides of the shaft. TWhen the latter is rotated by means of the driving gear, said beaters or blades are caused to revolve and open out in the container7 whereupon thev contents of the latter are thoroughly agitated and stirred.

Stops on the strip sides limit the opening of the beaters or blades to one way only.

The invention will be further described, with reference to the acconipanyingdrawing in which z- KFigure 1 is an elevation (broken) of a container, showing the apparatus fitted to the cover thereof.

Figure 2 is a cross sectional view of the cover and apparatus lit-ted thereto.,

Serial No. 418,404.

vFigure 3 is a vertical part section showing the mountingof the beaters or blades.

Figure #l is a cross section yof the upper end of a beater or blade.

Figure 5 is a further view in elevation illustrating the mounting, of the beaters or blades, and at right angles to Figure 3,

Figures 6, T and 8 are detail views of the driving wheel and parts iitted thereto.

ln the drawing 1 represents a` vessel or container, and 2 the cover or top thereof which in this case is a screw on top.

rllhe upper plate 3 is provided with a raised portion L1 and is secured to the lower plate 5 by screws 6, both plates being se'- cured to the cover 2 by screws and nuts 7.

The lower plate 5 is provided with a boss 8 on its under side, which projects downwards through the cover 2. The shortl central shaft 9 passes through the lower plate 5 and boss S thereof below the latter and also projects above the former, but does not pass through the upper plate 3.

The pinion 10 is lreyed on the upper end of the shaft 9, and gears with the toothed driving wheel 11, which with said pinion 10 is housed in the raised portion l of said plate 3.

A spindle 12 the base of which contains a cross groove 13 extends upwards through the boss 1-1 of the upper plate 3 and has a crank handle 15 mounted on its upper end.

The base of the spindle 12 fits into the central opening 16 of the wheel 11, the groove 13 fitting over the pin 17 which lays in grooves 18 in the wheel 11 so as to cross the opening 16.

llhe metal strip 19 is bent so as to have parallel sides and a connecting portion, the latter containing a central hole 2O which enables said strip to be passed on the shaft 9 below the cover 2, the distance between the sides of the strip being such that spaces 21 are left between the strip sides and the shaft 9. Y

The strip 19 is secured on the shaft 9 by a cross pin 22 which passes through. the Vstrip sides and the shaft 9 and screws into one of the former. The beaters or blades 23 are made preferably of wood and gradually widen towards their lower ends where they are rounded oli".

The small or upper ends of the beaters or blades 23 have secured thereon plates 24 which terminate at their upper ends in hooks 25 said plates being secured to the beater or blade ends preferably by having lingers or strips 26 which are bent around the beater or blade ends.

The beaters or blades 23 are pivotally secured one at each side of the shaft 9, by engaging the hooks 25 on the cross pin 22, in the spaces 2l between the sides oit the'strip 19 and shaft 9.

The beaters or blades 23 when revolved about nthe shaft 9 within the container or vessel l, by turning the handle l5, naturally tend to open or move outwards from each other so that the distance between said beaters or blades is determined by the speed at which the handle l5 is driven.

The person using the apparatus is thereby enabled tooperate the beaters or blades, to actV in or agitato the contentsof the vessel 0r container, near the cent-re thereof or at any distance from the centre according to requirements.

The beaters or blades 23 extend nearly to the bottom of the container or vessel and are limited by stops 27 on the lower ends of the sides of the strip 19 toopening'from each other in the one direction.

Having now particularly described and astalones Certained the nature of my said invention and in what manner the same is to be performed l decla-re that what l claim is 1. In an agitating device,`a rotatable shaft, an inverted U-shaped member having its crossliead arranged on said shaft, a cross pin carried by the shaft and extending through the legs of said U-shaped member, and blades having extensions pivotally mounted on said pin and arranged between the shaft and said legs. Y

2. ln a device of the kind deined by claim l, clamping members mounted on said extensions and gripping said blades.

3. A device of the kind defined by claim l i BASIL CARLISLE LOW. Witnesses:
